Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing detection systems fail to efficiently and effectively detect hazardous objects, such as explosive devices, in certain situations, particularly when they are accompanied by optical or electro-optical devices used by personnel.
Innovation Solution
The system employs a laser beam that is directed towards a target area and detects the retro-reflected laser beam to identify optically augmented reflections, which can indicate the presence of an explosive device or associated optical/electro-optical devices like binoculars, using a combination of a laser source, beam spoiler, detectors, and a control system to analyze the reflected beam and generate a histogram for target identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional detection systems are used to detect hazardous objects, then the detection process becomes complex and less effective, but using retro-reflection analysis with laser beams simplifies the system and improves detection efficiency
Solution Approach 1:
The patent extracts and isolates the retro-reflection characteristic as the key detection feature, separating it from complex multi-parameter analysis. By focusing solely on detecting the retro-reflected laser beam pattern, the system achieves high detection efficiency with minimal complexity, as the retro-reflection signature is unique and easily distinguishable from other reflections.
Solution Approach 2:
The patent introduces a laser beam as an intermediary tool to enable detection. Rather than using complex active sensors to probe targets directly, the system uses a passive laser beam that interacts with the target's optical properties, allowing detection of retro-reflection characteristics without requiring complex detection hardware.
2Reliability
If conventional detection methods are used, then direct detection of explosive devices is attempted, but detecting associated optical devices provides more reliable threat identification
Solution Approach 1:
The patent converts the presence of optical devices (which may be incidental rather than directly harmful) into a beneficial detection opportunity. By detecting the retro-reflection from binoculars, cameras, or other optical equipment, the system identifies threats indirectly through associated devices, making detection more reliable since these optical devices have distinctive retro-reflection signatures that are easier to detect than explosive devices themselves.

AI summary
In one embodiment, detecting a target includes directing a laser beam towards an area and detecting the laser beam reflected from the area. Whether the received laser beam comprises an optically augmented reflection indicating retro-reflection from a target is determined. The target indicates presence of an explosive device. The target is detected if the received laser beam comprises the optically augmented reflection.
